FirebaseStorage波德版(1.0.1)火力地堡存儲錯誤
var storageRef: FIRStorageReference! = FIRStorage.storage().reference()
let uploadTask = storageRef.putData(UIImagePNGRepresentation(image)!, metadata: nil) { metadata, error in
if (error != nil) {
} else {
let downloadURL = metadata!.downloadURL
print(downloadURL)
}
}
我簡單地從ImagePicker中選擇的圖像,並試圖將圖像數據保存到存儲火力。 。作爲火力文檔說明(從數據Docs Reference)上傳內存部分
它拋出以下錯誤:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[1]'
*** First throw call stack:

使用前的工作相同的代碼,我不知道現在的問題。
您是不是打印(圖片)? ..並驗證它是否爲零 –
